Vsync off and FPS capped at 64 ??.

[Gunnergolly]

Just tried turning Vsync off to see what kind of FPS my machine is capable of pushing out and noticed something a little odd.

 

No matter whether i'm in the cockpit view, external view or in the main menu view my FPS is always 64. With Vsync turned off i was expecting the FPS to fluctuate/vary depending on what's being rendered and especially to max out when viewing the aircraft externally with no other scenery present other then blue sky.

 

At the very start of a mission or if i pause the mission whilst playing the FPS counter jumps to 180, as soon as i start/unpause it immediately drops to 64FPS.

 

It's exactly the same with V2.03, my FPS is capped at 64 ?.

 

The common denominator is my Nvidia 970 graphics card, i've tried various settings but there is no change. I'm guessing that you have to play in "full screen" mode for them to take effect anyway ?. Unfortunately i can't use full screen mode as i export onto a second monitor and i can no longer use SoftTh.

 

Any ideas/suggestions why my FPS is always capped at exactly 64 with Vsync turned off on both 1.5.4 and 2.0.3 ?.

 

Thanks.

64 fps MAX !?

 

I have exactly the same issue. FPS limited to 64 even V-sinc OFF. I managed to restore it to about 180 wich is my random FPS before this bug but only for one time and it returns to 64 limited. It makes me sad :joystick:

 

my config : i5 2500k 4.4Ghz 16 Gb RAM GTX970

 

Please HELP !

Unless you have a 100 Hz screen, why is having frame rates capped to 64 Hz an issue?

 

Your screen won't be capable of rendering any more frames if you have a 60 Hz screen.

[IJG2_Bouma]

My screen is a 120hz and when this bug dose not appear i am usually over 150FPS. I think this is a very important issue related to the optimization of DCS.

[NeilWillis]

Well, that is an entirely different matter.

FPS Still locked by the options in your DCS autoexec.cfg maybe.

 

c:\Users\Username\Saved Games\Dcs\Config\Autoexec.cfg

 

 

 

--*******************

--*******************

--** Begin Changes **

--*******************

options.graphics.render3D = true; -- Set this to false for a standalone Server Setup.

options.graphics.maxfps = 120; -- DCS 1.2x 0=unlimited FPS, DCS 1.5x or 2.x 0=0 FPS for load screen, news screen jerky.

No there is no such file in my config folder. I am back to an older version of 1.5.4 and now i am limited to 120 Fps even with V sinc OFF ! something is still wrong...

[IJG2_Bouma]

AMAZING ! just try to show FPS with Shadow play and RECORD ! your FPS Will Explode ! the game became very smooth. the DEVS must take that in consideration for next patchs

I'm no longer using the Autoexec.cfg file with 1.5.4 or 2.0.3, but thanks for the suggestion.

 

I have just installed Shadow play and my FPS has doubled with Vsync turned off to 120. I went for a ride in the L-39 straight down the Las Vegas strip with Vsync turned on and my FPS never moved from 60.... very smooth flight.

 

Also tried the instant action Mig-21 "free flight" mission in 1.5.4 which normally starts with an FPS of around 54, this time my FPS was a constant 60 (Vsync on) and once again another very smooth flight.

 

Nice find I/JG2_Bouma and a pleasant surprise, i will test some more when i have time.

 

Thanks.

Hello,

 

I am trying to get my head around this... you are using Shadow Play, now known as Share in Geforce Experience?

 

Thanks for any help. The Nvidia site is a bit confusing and it wants me to log in using my FB account to use this feature(?).

[Gunnergolly]

Hello JG14_Smil

 

I downloaded Shadow play from this link:-

 

http://nvidia-geforce-shadowplay.en.softonic.com/

 

Close down the add that appears and press the big free download button.

 

I have never used this program before and it appears to be part of the "Geforce Experience" program/package.

 

Click on the "Shadow play" button on the top right menu bar and turn it on.

 

Start up DCS.

 

I can't play in full screen mode because i export on to a second screen so i have to "alt tab" twice...... otherwise my exports are "mushed" up on to my main view.

 

I now have very smooth gaming and if i turn Vsync off my FPS is no longer capped at 64 but is now 140+ ?????..... magic .... almost to good to be true :).

 

I didn't have to log into facebook to use this feature.

 

Once you have it sussed out then let us know if it helped.

 

Regards.

Thanks for the detailed answer Gunnergolly. This is very exciting and a much needed SoftTH replacement for the multi monitor setup. I'll report my findings soon.

[IJG2_Bouma]

I hope the devs of ED can do something to run the game smoothly without shadowplay running. I don't want to record all my failings and crashes lol and my HDD is not so big capacity...

[JG14_Smil]

Man, I do hate those download sites! They are like minefields trying to choose the correct link.

 

Your link took me to a page where I finally DL'd "GeForce_Experience_v2-4-5-28.exe". (?)

 

My computer won't let it load as it says I have a same or newer version. If I start my Geforce Experience up, it asks me to log on using an account, I don't see any Shadow Play buttons.

 

I don't see why I must use a Facebook account just to use this on my system. Is the Shadow Play icon that human head silhouette in a gray circle? I cannot use it until I log in with the account.

I/JG2 Bouma: People have been wishing that for a long, long time. :)

Hello fellow humans. Ive had a issue with this and all I did was on windows 10 to open the xbox app and deactivated the DVR in settings. This was somehow activated by default in my latest update. It made my refreshrate to half of what it should be. Same goes for my son who got 30 frames but should 60.

[hughlb]

I can also confirm that the sim (1.5.4, and 2.0.3) runs with less stuttering when recording a video at 60fps with Fraps. Yes that's right, when RECORDING full HD video, I got less stuttering.

 

I also deleted the "Max FPS" value, entirely, from the graphics.lua, which also helped improved stuttering slightly - all very strange. I've taken a ticket out with ED, which has proven to not yet provide a diagnosis of the problem - I appreciate their help so far though.

Yes that is the correct version.

 

I was a bit hesitant to download from that site myself but glad i did, if it's all working properly then you should be seeing what i have in my attachment below.

 

All i did was to click on the top bar "preferences" button.

 

Select the "ShadowPlay" tab on the left hand side of the screen.

 

Press the FPS button and select it's position on screen.

 

Click on the top bar "Shadowplay" button with the camera icon on it (top right corner).

 

Another window should appear with a switch, turn it on.

 

Then play DCS, you will probably have to "alt - tab" DCS to get it working.

 

If it's saying that you already have that version installed then maybe try uninstalling it and use CCleaner (free) to clear out your registry and then reinstall.

I'm guessing that Shadowplay is now filling my little hard drive up with recordings so i need to find out where it's storing them and periodically keep deleting them.

 

Hope the above helps you.

I have tried what you suggested with Shadowplay and there is no changes in FPS at all. Absolutely no changes.

[IJG2_Bouma]

This is a video to show the effects of Shadowplay on DCS.

 

It seems to work With OBS too !

 

 

I found a trick to run DCS world very smooth with more than 100 FPS.

 

My Config PC : i5 2500k / 8GB RAM / GTX 970

 

By recording with Nvidia Shadowplay something seems to be unlocked on DCS and the FPS double immediately !

 

Nothing to do with Xbox app DVR wich is already OFF.

I have seen your video already. I am not the only one but no one of the people I know have been able to increase DCS FPS. Your video do not explain anything and it can be a fake !

[IJG2_Bouma]

Troll detected ! bip bip bip

[Gunnergolly]

Thanks for the video I/JG2_Bouma

 

That's exactly whats happening with mine, with Shadowplay turned off my FPS is capped at 64, Shadowplay turned on then i'm getting at least double that.

 

Why that is the case i really don't know ??, but i'm not complaining :).
